Finding Rayquaza, however, is simple compared to battling and catching this legendary beast. Here are some tips that can help you add Rayquaza to your Pokédex in Pokémon Go.

Battling Rayquaza

Before you can even consider trying to take on Rayquaza, it's important to find other trainers who can help with this raid battle. A large number of fellow trainers participating in a legendary raid battle will greatly increase your chances of successfully defeating that Pokémon.

Next, you'll need to assemble your best lineup of Pokémon in order to take down Rayquaza. Pokémon Go trainers can use up to six Pokémon in raid battles. You'll have about two minutes to put together your team of Pokémon before entering the five-minute battle with Rayquaza.

Make sure to keep Rayquaza's weaknesses in mind when creating your team of Pokémon for this battle. Rayquaza is a Dragon and Flying-type Pokémon, which means that its weak against Ice-type, Dragon-type, Fairy-type, and Rock-type moves. Additionally, Ice-type moves will be best to use on Rayquaza because they're four-times super effective against it.

Thus, you should bring a lineup predominantly built around strong Ice-type Pokémon, including Articuno, Lapras, Walrein, Jynx, Cloyster, and Piloswine. If you can't build a full Ice-type Pokémon lineup, you can fill the gaps with creatures that target Rayquaza's other weaknesses, including Dragonite, Golem, Rhydon, Tyranitar, and Gardevoir. A Kyogre that knows Blizzard as it's charged move is also a decent option for this raid battle.

Rayquaza can know Dragon Tail and Air Slash as its two fast attacks, while its charged move can be Outrage, Ancient Power, or Aerial Ace. Ancient Power, a Rock-type move, will obviously deal a ton of damage to Ice-type Pokémon—so if you have a full Ice-type team, pray to the Pokémon Go gods that the Rayquaza you're battling knows Aerial Ace or Outrage. If Rayquaza knows Outrage, however, it'll be lethal against any of your Dragon-type Pokémon.

This definitely won't be an easy fight, but assembling your strongest lineup of Pokémon and battling alongside several other trainers can significantly improve your odds of defeating Rayquaza. Once you take down this legendary Pokémon, the next step is to try to catch it.

Catching Rayquaza

When a raid battle is completed, each participating trainer will be rewarded with individual in-game items. Trainers will then receive a certain number of Pokéballs in order to try to catch a weaker version of the raid boss.

We strongly recommend using Golden Razz Berries during the catching phase of this raid battle—they'll greatly increase your chance of capturing Rayquaza. This legendary Pokémon is huge, but not necessarily as difficult to catch as Kyogre. Rayquaza just slightly floats up and down, and it has a relatively big circle size to throw Pokéballs at.

If you use Golden Razz Berries and aim for an excellent throw, you'll give yourself the best chance to add Rayquaza to your Pokédex.

Good luck, trainers—Rayquaza will be available in Pokémon Go until March 16.
